iphone storage is full

Hi everyone,

I have a 32GB iphone 7 running version 10.1.

Recently I'm constantly getting "iphone storage is full" messages. I deleted some apps and media files (photos and videos) multiple times. When i delete some items it shown that there is some memory free, but after a short time it's getting back to 0 kb. in the last week i deleted items of more than 1GB, but still wend back pretty quickly to 0, without adding any new large files/apps.

I tried also the "hard restart" to clear to cache, but it didn't help.

When i check the storage details, the total memory usage of all apps (including the photos & camera) is about 16GB, but it still shows at the top that 27.59 GB used and there is 0 KB available.

Does anyone experience such as issue?

Thanks,

Or
